inaccessible AIJ file forced image exit to protect database

  Explanation:  To maintain the integrity  of  the  database,  the
  database  system  has  forced  your image to exit.  An error has
  been encountered with one or more of  the  after-image  journals
  that  could  jeopardize  your  ability  to  recover the database
  should  a  it  become  necessary  to  restore  and  recover  the
  database.   Until  the  journaling  problem has been remedied no
  further updates to the database are allowed.

  User Action:  The RMU or DBO /DUMP/HEADER=JOURNAL  command  will
  display the current state of the journals.  Various remedies are
  possible, depending on the error  encountered.   Contact  Oracle
  Support  if  you  have  questions  on  how  to  fix the problem.
  Typically, disabling and re-enabling journaling is the  simplest
  way  to  restore  operation  of  the database.  This can be done
  using the DBO or RMU SET AFTER command, or from interactive SQL.
  After  the  journaling problem has been resolved a full database
  backup must be done to ensure that the database can be  restored
  and recovered successfully in the future.
